Understanding Carbon-in-Leach (CIL) Processing

Carbon-in-Leach is a proven gold extraction method that dissolves gold from ore using a cyanide solution, with activated carbon added directly to the leach tanks to adsorb the dissolved gold. This technology is particularly well-suited to Brightstar's ore types and represents the industry standard for large-scale gold processing in Western Australia.

The CIL process offers superior gold recoveries, operational flexibility, and the ability to process varying ore grades and types, making it ideal for Brightstar's multi-mine operation across the Goldfields Hub. The method involves crushing ore to optimal size, mixing with cyanide solution in agitated tanks, and using activated carbon to capture dissolved gold before final processing into doré bars.

Diversified Mining Portfolio Underpins Production Profile

Brightstar's production strategy leverages a diversified portfolio of four mining operations across the Laverton and Menzies hubs, providing operational flexibility and risk mitigation. However, this approach also requires careful coordination to optimise ore sequencing and maintain consistent feed grades to the processing facility.
